In its official statement, the UNESCO justified its selection, stating »the Bauhaus, with its sites in Weimar (Thuringia) and Dessau (Saxony-Anhalt), represents the so-called Bauhaus school of architecture which, between 1919 and 1933, applied revolutionary ideas to building design and town planning. The buildings of the Bauhaus professors, from Walter Gropius to Hannes Meyer, Lazlo Moholy-Nagy to Wassily Kandinsky, founded the Bauhaus style, which made a decisive mark on the architecture of the 20th century.«
